Answer:
An enzyme is a molecule that speeds up a reaction. In the case of DNA reproduction, enzymes not only speed up the reaction, they are necessary for DNA reproduction.
Explanation:
An enzyme is a molecule that speeds up a reaction. In the case of DNA reproduction, enzymes not only speed up the reaction, they are necessary for DNA reproduction.
Recall that DNA is a long strand with a many repeating base pairs. In order for DNA to reproduce, the base pairs must be split apart. One half of the strand is then used as a template to build a new strand of DNA.
The enzyme helicase is responsible for splitting DNA along the base pairs. Helicase moves along the DNA strand unzipping the strand just as a zipper.
The second sentence is correct if you mean lipids and proteins as 'materials'
This is C)chemical change
For example combustion where an organic compound is turned into CO2 and water.
Hello!!
A: Anaphase — 1 chromatids move towards opposite poles. I always remember that “Ana” moves to different places on the sides of town. This is where the chromatids begin to move.
B: Telophase — 4 Cytokinesis may occur. Cytokinesis is the last and final step. The sister chromatids finish moving towards the poles and then cytokinesis occurs.
C: Metaphase — 3 Chromatids line up in the middle of the cell. I always remember since they line up in the middle, they “met” there.
D: Prophase — 2 and 5 Disintegration of the nuclear membrane and the spindle forms. Both of these have to happen first in order for the rest of the processes to occur.
**The order of mitosis goes prophase, prometaphase, Metaphase, Anaphase, Telophase, and Cytokinesis.**
For the bottom:
A: Algae 6 and 10. Both diatoms and kelps (plant related) are a part of the Algae general type.
B: Fungi 7 and 9. Deuteromycetes and Ascomycetes.
C: Protozoa 8. It is ciliates because they are a major group of Protozoa from cilia.
I hope I helped!! Have a great day!! :)
